Description

Technical Field

[0001] This utility model belongs to the field of rubber production wastewater treatment technology, and in particular relates to a rubber production wastewater treatment device. Background Technology

[0002] Synthetic rubber is polymerized from petrochemical intermediates and is mainly used in the manufacture of automobile tires. It is also widely used in rubber shoes, hoses, belts, sheets, cables, and medical devices. The wastewater generated during the synthetic rubber production process is large in volume and highly toxic; if discharged directly without treatment, it will seriously pollute the ecological environment.

[0003] In the prior art, Chinese utility model patent CN211328276U discloses a treatment device for rubber production wastewater, relating to the field of rubber production technology. The device includes a treatment tank, with an inlet pipe fixedly connected to the upper end of the tank. A chemical solution pipe is connected to the outer side of the inlet pipe. The lower end of the inlet pipe penetrates the upper surface of the treatment tank and extends into its inner cavity. A sleeve is movably sleeved to the outer side of the lower end of the inlet pipe via a bearing. A rotating shaft is installed inside the sleeve, and blades are fixedly connected to the upper outer wall of the rotating shaft. The blades are arc-shaped, and one end of each blade is fixedly connected to the inner wall of the sleeve. This utility model utilizes multiple blades arranged in a circular array fixedly connected to the upper end of the rotating shaft, and multiple sets of agitating rods fixedly connected to the lower end of the shaft. After the wastewater and chemical solution are mixed, they impact the blades, causing the blades and agitating rods to rotate. The rotation of the agitating rods stirs the wastewater, thereby ensuring thorough and uniform mixing of the wastewater and chemical solution, thus improving the sedimentation effect of the wastewater.

[0004] In existing technologies, multiple blades arranged in a circular array are fixedly connected to the upper end of a rotating shaft, and multiple sets of stirring rods are fixedly connected to the lower end of the rotating shaft. This allows the wastewater and the chemical solution to be fully and uniformly mixed, thereby improving the sedimentation effect of the wastewater. However, there are still some shortcomings in its overall use:

[0005] First, rubber wastewater will produce precipitates after being mixed with chemical solutions. Direct discharge without dewatering has certain drawbacks. Due to the high water content and large volume of sludge, transportation and disposal are difficult. Improper sludge treatment may also cause secondary pollution.

[0006] Secondly, the wastewater generated from rubber processing contains impurities removed from the crude rubber during cleaning. These impurities include particulate matter. If the particulate matter is not filtered, some fine or incompletely settled particulate matter may still remain in the water after flocculation and sedimentation, resulting in incomplete purification and wear on the treatment equipment, thus shortening its service life. Utility Model Content

[0007] This invention addresses the technical problems of rubber wastewater sludge having high water content, large volume, making transportation and disposal difficult, and the inability to remove particles leading to incomplete purification and wear on treatment equipment. It provides a rubber production wastewater treatment device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a rubber production wastewater treatment device, comprising a tank, a filtration mechanism at the top of the tank for filtering particulate impurities in the wastewater, a flocculation component inside the tank and below the filtration mechanism for flocculating and settling impurities in the wastewater; a dewatering tank fixedly installed inside the tank below the flocculation component, one end of the dewatering tank penetrating one side of the tank, a drain plate fixedly installed at the bottom of the dewatering tank for draining the filtered water, and a pressure plate slidably installed inside the dewatering tank for pressing and filtering sludge;

[0009] Below the drain plate is a sliding plate that slides inside the chamber. The top of the sliding plate is fixedly installed with multiple top posts that cooperate with the mesh at the bottom of the dehydration chamber. The top posts are cone-shaped.

[0010] The sludge is pushed forward by the pressure plate to the end of the dewatering tank, and the water in the sludge is filtered out. At the same time, the sludge is compressed into blocks, reducing its volume and moisture content, making it easier to collect, process and transport. During sludge filtration, water can be discharged from the through holes of the drain plate. After filtration is completed, the pressure plate returns to its original position, and the slide plate moves upward under the reset action of the spring, inserting the top column into the through holes of the drain plate to remove the sludge that is clogging the through holes, preventing blockage and ensuring that water can be discharged, thus improving the sludge filtration effect.

[0011] In the aforementioned rubber production wastewater treatment device, the filtration mechanism includes a filter box fixedly installed in the upper part of the inner cavity of the housing. The filter box is arched and used to move the filtered impurities to both sides. Openings penetrating the housing are provided on both sides of the filter box.

[0012] Wastewater is filtered through a filter box to remove particulate matter. Because the filter box is arched, the filtered particulate matter moves to the sides of the filter box, preventing it from clogging the filter box and improving the filtration effect.

[0013] In the aforementioned rubber production wastewater treatment device, insert plates for sealing the opening are slidably installed on both sides of the box body, and collection boxes communicating with the opening are fixedly installed on both sides of the box body.

[0014] The collection box allows for the timely removal of filtered impurities, preventing excessive clogging of the filter box and facilitating collection, thus improving filtration efficiency.

[0015] In the aforementioned rubber production wastewater treatment device, the flocculation component includes a flocculation tank fixedly installed on the back side of the tank for introducing flocculant into the tank. Below the filter box, a stirring chamber fixedly installed inside the tank is provided. The bottom of the stirring chamber is semi-circular. A rotating shaft is rotatably installed inside the stirring chamber. Multiple stirring rods are fixedly installed on the surface of the rotating shaft for stirring the wastewater and flocculant.

[0016] Flocculant is added to the tank to accelerate the sedimentation of impurities in the wastewater. The motor drives the shaft to rotate, which in turn drives the stirring rod to stir the wastewater and flocculant, so that the flocculant and wastewater are fully mixed and the sedimentation speed is accelerated.

[0017] In the aforementioned rubber production wastewater treatment device, a bubble baffle is fixedly installed on the top of the mixing chamber.

[0018] The bubble baffle blocks the air bubbles generated when the wastewater is stirred. Too many air bubbles may occupy the effective volume of the sedimentation tank, interfere with the sedimentation effect, and result in the effluent water quality not meeting the standards.

[0019] In the aforementioned rubber production wastewater treatment device, the inside of the bubble baffle is provided with multiple through holes, and multiple cutting lines are fixedly installed inside the through holes.

[0020] By cutting the air bubbles generated during the mixing of wastewater with a cutting line, foam can be eliminated, thereby improving the wastewater treatment effect.

[0021] In the aforementioned rubber production wastewater treatment device, a support plate is fixedly installed in the inner cavity of the tank below the mixing chamber. A sludge suction pump is fixedly installed on the lower surface of the support plate. The inlet end of the sludge suction pump is connected to the mixing chamber, and the outlet end of the sludge suction pump is connected to the dewatering tank.

[0022] In the aforementioned rubber production wastewater treatment device, a spring is fixedly installed between the lower surface of the slide plate and the upper surface of the inner cavity of the box.

[0023] In the aforementioned rubber production wastewater treatment device, a vibrating motor is fixedly installed on one side of the dehydration tank, and a baffle is hinged to the lower surface of the end of the dehydration tank near the vibrating motor.

[0024] The sludge, which is extruded and shaped by a vibrating motor, is detached from the inner wall of the dewatering tank. When the baffle is opened, the shaped and dried sludge is discharged from the dewatering tank, which is convenient for collection and greatly improves work efficiency.

[0025] In summary, compared with the prior art, the rubber production wastewater treatment device provided by this utility model has the following beneficial effects:

[0026] 1. This utility model, through the setting of dewatering tank, drain plate, pressure plate, slide plate, top column and spring, can flocculate the impurities after sedimentation and perform pressure filtration, so that the sludge can reduce the water content and volume, making it easier to collect, transport and process later. At the same time, it can clean the drain holes to avoid clogging, which greatly improves the efficiency of wastewater treatment.

[0027] 2. This utility model, through the setting of filter box, opening, insert plate, fixing plate, cylinder and collection box, can pre-treat wastewater, filter particulate impurities in wastewater, collect them, and discharge filtered impurities in a timely manner, avoiding excessive impurities from clogging the filter box and improving the filtration effect.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0036] refer to Figures 1-4A rubber production wastewater treatment device includes a housing 10, a detachable top cover 11 on the top of the housing 10, an inlet pipe 12 connected to the top of the top cover 11, and an arched filter box 13 fixedly installed inside the top cover 11.

[0037] Specifically, rubber wastewater enters the housing 10 through the inlet pipe 12. The filter box 13 filters the wastewater, removing particulate impurities. Because the filter box 13 is arched, the filtered particulate impurities move to both sides of the filter box 13, preventing them from clogging the filter box 13 and improving the filtration effect.

[0038] Further reference Figure 4 The filter box 13 has L-shaped openings 14 on both sides that penetrate the box body 10. The outer side of the box body 10 is slidably installed with a sealing plate 15 for the opening 14. The two sides of the box body 10 and above the sealing plate 15 are fixedly installed with a fixing plate 16. The upper surface of the fixing plate 16 is fixedly installed with a cylinder 17. The output end of the cylinder 17 penetrates the fixing plate 16 and is slidably engaged. The lower surface of the cylinder 17 is connected to the upper surface of the sealing plate 15. The outer side of the box body 10 is fixedly installed with a collection box 18 that communicates with the opening 14. The sealing plate 15 slides inside the collection box 18.

[0039] Specifically, the impurities filtered by the filter box 13 gather in the opening 14. The cylinder 17 can be controlled to pull the insert plate 15 upward, thereby causing the insert plate 15 to slide upward and release the sealing state of the opening 14, allowing the impurities to enter the collection box 18 for collection. This can promptly discharge the filtered impurities, prevent excessive impurities from clogging the filter box 13, facilitate collection, and improve the filtration effect.

[0040] Further reference Figure 3 and Figure 4 Below the filter box 13, there is a mixing chamber 19 fixedly installed inside the box body 10. The bottom of the mixing chamber 19 is semi-circular. A rotating shaft 21 is rotatably installed inside the mixing chamber 19. Multiple stirring rods 22 are fixedly installed on the surface of the rotating shaft 21. A motor 20 for driving the rotating shaft 21 is fixedly installed on the outside of the box body 10. A flocculant tank 26 is fixedly installed on the back side of the box body 10 for adding flocculant into the box body 10.

[0041] Specifically, when adding wastewater to the tank 10, flocculant is also added inside the tank 10 to accelerate the sedimentation of impurities in the wastewater. The motor 20 drives the rotating shaft 21 to rotate, which in turn drives the stirring rod 22 to rotate and stir the wastewater and flocculant, so that the flocculant and wastewater are fully mixed and the sedimentation speed is accelerated.

[0042] Furthermore, refer to Figure 4 and Figure 5A bubble baffle 23 is fixedly installed on the top of the mixing chamber 19. The bubble baffle 23 has multiple through holes 24 inside. A cutting line 25 is fixedly installed inside the through holes 24 to cut the bubbles generated when mixing wastewater.

[0043] Specifically, the bubble baffle 23 is used to block the bubbles generated when mixing wastewater. Too many bubbles may occupy the effective volume of the sedimentation tank, interfere with the sedimentation effect, and cause the effluent quality to fail to meet the standards. The cutting line 25 is used to cut the bubbles generated when mixing wastewater, eliminate foam, and improve the wastewater treatment effect.

[0044] Further reference Figure 3 and Figure 4 Below the mixing chamber 19, there is a support plate 28 fixedly installed inside the box 10. A sludge suction pump 29 is fixedly installed on the lower surface of the support plate 28. The inlet end of the sludge suction pump 29 is connected to the mixing chamber 19 and is used to remove the sludge settled in the mixing chamber 19. The back side of the box 10 is connected to a first drain pipe 27 for discharging the filtered water after flocculation and sedimentation.

[0045] Further reference Figure 3 , Figure 4 and Figure 6 Below the sludge pump 29, a dewatering tank 30 is fixedly installed inside the housing 10. The upper surface of the dewatering tank 30 is connected to the outlet end of the sludge pump 29. A drain plate 31 is fixedly installed at the bottom of the dewatering tank 30. A hydraulic cylinder 32 is fixedly installed on one side of the housing 10. The output end of the hydraulic cylinder 32 passes through the housing 10 and the dewatering tank 30 and is slidably engaged. A pressure plate 33 that slides inside the dewatering tank 30 is fixedly installed at the end.

[0046] Specifically, the sludge suction pump 29 sucks the sludge settled in the mixing chamber 19 into the dewatering tank 30. After the operation is completed, the hydraulic cylinder 32 pushes the pressure plate 33 forward to squeeze the sludge, pushes the sludge to the end of the dewatering tank 30, and filters out the water in the sludge. At the same time, the sludge is squeezed into blocks to reduce its volume and moisture, making it easier to collect, process and transport.

[0047] Further reference Figure 3 , Figure 4 and Figure 6 A sliding plate 34 is slidably installed inside the box body 10 below the dewatering tank 30. A spring 36 is fixedly installed between the lower surface of the sliding plate 34 and the upper surface of the inner cavity of the box body 10. A top column 35 is fixedly installed on the upper surface of the sliding plate 34 and inserted into the through hole of the drain plate 31. This is used to clean the sludge in the through hole of the drain plate 31 and prevent blockage that would prevent the filtered water from being discharged. The length of the top column 35 is higher than the upper surface of the drain plate 31. The top column 35 is usually conical. A second drain pipe 37 is connected to the bottom of the box body 10 for the discharge of filtered water.

[0048] Specifically, when the pressure plate 33 squeezes the sludge for filtration, the pressure plate 33 simultaneously squeezes the top column 35, causing the top column 35 to move downwards. This allows water to be discharged from the through holes of the drain plate 31 during sludge filtration. After filtration is completed, the pressure plate 33 returns to its original position, and the slide plate 34 moves upwards under the reset action of the spring 36, inserting the top column 35 into the through holes of the drain plate 31. This removes the sludge that is clogging the through holes, preventing blockage and ensuring water can be discharged, thus improving the sludge filtration effect.

[0049] Further reference Figure 4 and Figure 6 The dewatering tank 30 extends through one side of the box body 10, and an L-shaped baffle 39 is hinged to the bottom of the end of the dewatering tank 30. A pin is provided at the bottom of the baffle 39 to fix the baffle 39 to the box body 10, so that the baffle 39 and the dewatering tank 30 are sealed. A vibration motor 38 is fixedly installed on the side of the dewatering tank 30 near the baffle 39, which is used to detach the extruded sludge from the inner wall of the dewatering tank 30, so that when the baffle 39 is opened, the formed dry sludge is discharged from the dewatering tank 30, which is convenient for collection and greatly improves work efficiency.
